Definitions

  • the invention relates to a device for rearing aquatic organisms on the ground with a container which fills the water organisms and is filled with water Arrangements are provided.
  • the solution to the problem is inventively characterized in that the slip receptacles, which are tubular or the like., Open and fastened with their head ends to a support base which separates a fresh water tract from a dirty water tract within the container, so that the slippage receptacles directly from the from the fresh water supplied side of the carrier floor are guided into the water of the dirty water tract, and that the dirty water ends of the individual slip receptacles are provided with constrictions to prevent the water organisms from escaping.
  • the invention is defined in claim 1 and the subclaims relate to the preferred features of the invention.
  • the hatches will consist of tubes, which usually and preferably extend obliquely upwards.
  • the hatchings consist of tubes, which are generally and preferably arranged horizontally.
  • the oxygen-rich, clean breathing water flows from the front head end of the tubes to the rear or lower narrowed tube end. The constrictions are kept so that excrement and feed residues can leave the tubes at the rear or rear end, but the aquatic organisms are retained.
  • the carrier base can, for example, float in the water or be fastened to the wall of the container.
  • the size of the support base is arbitrary and depends on the handling. Carrier bottoms with different tube sizes can also be kept ready for the different stages of breeding of eels, crabs or other aquatic organisms to be reared.
  • the eels will usually stand upside down in the tubes, while the crabs will normally crawl in the horizontal tubes. In both cases, this resting position corresponds to the habits of the animals, so that animal-appropriate rearing is possible.
  • Crabs and eels in particular, but also other aquatic organisms that live in caves and soils, can preferably be reared in warm water. In northern latitudes, this means providing warm rearing water. This is possible by heating the rearing water.
  • Warm waste water which is constantly available in various industries, is of particular importance. Apart from very clean water, there are two different types of waste water. One wastewater is dirty, but the dirt content is of such a nature that it is easily possible to feed a dirty water tract directly with it.
  • the support base can only consist of a plate on which the slip receptacles open and are attached with their upper or front ends. The tube walls then protrude into the dirty water tract, the dirty water flushing around the tubes and heating them to the desired extent.
  • the support base consists of a hollow body through which the slip receptacles pass. This dirty water thus only serves to warm the hatchings and leaves the device without coming into contact with fresh water or dirty water in the dirty water tract.
  • Fig. 7 shows the principle of the device for raising eels or other aquatic organisms living on the ground, which have the tendency or the habit of being in tubes.
  • the device consists of a support base 1 in which a large number of slip tubes 3 are fastened.
  • the rear ends 7 are narrowed by bending an edge part 9 or the like in such a way that liquid as well as feed residues and excrement can be drawn off through the remaining opening 11, but an eel 12 cannot escape.
  • the eels are kept in such a way that fresh water 13 is supplied above the carrier floor 1. This fresh water flows in the direction of an indicated arrow 75 through the hatch tube 3 and leaves it below the support base 1 at the opening 11, for example by the water 17 below the support base 1 under a certain negative pressure is set. Excrement products and others removed through opening 11. The eel 12 is therefore always provided with clean breathing water.
  • a container 19 is shown, in which a support base 1 is located.
  • This support base 1 connects with its edges 21 directly to the container 19, so that a fresh water tract 23 with fresh water 13 is formed above the support base 1, while a dirty water tract 25 with the dirty water 17 is provided below the support base.
  • the fresh water 13 is entered via an inlet 27. Since the dirty water is discharged via a channel 29, a suction is created which allows the fresh water to flow through the hatch pipes 3.
  • a water circulator 31 is also provided, which circulates and aerates the water in the fresh water tract 23.
  • FIG. 3 an apparatus for growing cancers.
  • a support base 101 is provided, in which slip tubes 103 are inserted.
  • the hatch pipes 103 are fixed with their head ends 105 in the support base 101 and open into the fresh water tract 123.
  • the rear ends of the hatch pipes 103 are so narrowed that contaminated water with faeces and feed residues can be drained through them, but that crabs sitting in the hatch pipes 112 cannot leave the hatch tubes.
  • the fresh water contaminated by faeces and feed residues leaves the hatch pipes 103 at the opening 111 because the water 117 in the dirty water tract 125 is under negative pressure.
  • the hatch pipes 103 constantly flow through fresh water, and the crayfish 112 in the hatch pipes 103 live in an environment which is comfortable for them and which is comfortable for them.
  • the carrier base 101 is designed as a tube, and the fresh water tract 123 is located in its interior.
  • the hatch pipes 103 extend outward from the tubular support base 101 into the dirty water tract 125, which is surrounded by a tubular jacket 119.
  • other configurations of the device for growing crayfish are also conceivable.
  • FIG. 5 shows a variant of the device for pulling up eels with a support base 201, which can be designed as a solid base, for example in foam plastic.
  • This support base 201 has a thickness d which is dimensioned such that the hatch tubes 3 for eels, as shown in FIG. 1, are received in full length in the support base 201.
  • the carrier base 201 is located in a water container 219, into which fresh water 13 is supplied via a line 227 above the carrier base 201.
  • a fresh water tract 223 is again formed above the carrier base 201 and a dirty water tract 225 below the carrier base 201.
  • the fresh water flowing through the hatch pipes 203 is sucked off into the dirty water tract 225 and takes with it impurities such as faeces and feed residues.
  • the negative pressure in the dirty water tract 225 can arise in that the dirty water 17 is sucked out of the device via a nozzle 229.
  • Warm industrial wastewater is often available in industry and is discharged unused into drain pipes. In northern latitudes, normal fresh water is relatively cold and its temperature is therefore not optimal for the eels, crabs or other soil-dwelling organisms living in warm regions, so that e.g. waxing out is slower than the optimum temperature. It is possible to use warm industrial wastewater to bring both the fresh water and the hatch tubes to a temperature that is comfortable for the animals.
  • Fig. 6 an embodiment is shown which provides for the use of warm industrial waste water, although this warm industrial waste water is not suitable as fresh water, Sedoch is quite suitable for removing excrement, feed residues or other contaminants.
  • there is a carrier base 301 inside the water container 319 which is designed like the carrier base 1 in FIGS. 1 and 2.
  • Slip pipes 303 are thus fastened to the carrier base 301 with their head pieces 305 in an inclined position.
  • Fresh water 13 is located above the carrier base 301 and is circulated in a circulator 331. Fresh water is supplied via an inlet pipe 327.
  • Dirty water 317 is introduced into the dirty water tract 325 via a separate inlet 335.
  • This dirty water is a warm industrial waste water, which is brought in, for example, from dairies or the like.
  • This warm industrial waste water heats the carrier base 301 and, via it, the fresh water 13 and the hatch pipes 303.
  • the heat transfer is indicated by arrows K. This brings the entire device for raising eels, which is of course also possible when rearing crabs, to an optimal water temperature for the animals.
  • the dirty water is sucked off via a dirty water connection 319, as in the previously described devices. or derived.
  • the circulation of the warm waste water introduced within the dirty water tract is indicated by arrows J.
  • the in the device of FIG. 6 for Dirty water used has a degree of pollution that makes it possible to subject the dirty water together with the excrement to normal wastewater treatment. There is also warm sewage water that is so contaminated that it cannot be brought into contact with fish or fish farming at all. Such dirty water can still be used in the device according to FIG. 7.
  • a carrier base 401 is arranged in the water container 419, through which the slip tubes 403 extend from the fresh water side 437 to the dirty water side 439 in the inclined position already described above.
  • Fresh water 13 flows into the fresh water tract 423 via an inflow pipe 427.
  • a circulator 431 ensures that the fresh water is circulated in the fresh water tract 423.
  • the fresh water 13 thus flows through the hatch pipes 403 again from top to bottom and takes excrement, feed residues and other contaminants into the dirty water tract 425, from which they are discharged via the suction line 429.
  • the interior 439 of the carrier base 401 is connected to a dirty water line 441. Warm dirty water, which is completely unsuitable for fish, flows into this interior 439 via this dirty water line 441, which is heated thereby.
